Title: Delayed switchgear with bimetal switch - has thermal coupling between bimetal switch and thermistor
Inventor: KRIWAN FRIEDRICH
IPC: H01H43/30
Filed: 1977-05-06
Abstract: The delayed action of the switchgear is provided by delayed actuation of the bimetal switch (B1) which is thermally coupled to a thermistor (T1). The thermistor mass is preferably considerably greater than that of the bimetal switch. The thermistor may have positive or negative temperature coefficient. The switching temperature of the bimetal switch is typically 25 to 50% of the thermistor final temperature. The connection between the switch and thermistor may be via strips (S1) of defined, limited thermal conductivity. Alternately several bimetal switches may cooperate with one or several thermistors. If the delay is controlled by a pulse the thermistor is incorporated in the control pulse circuit, while the bimetal switch forms part of an operational circuit.

Title: Load monitoring circuit for security alarm system - ensures that release of load causes cable to complete electrical alarm circuit
Inventor: LINK ERICH
IPC: G08B13/12
Filed: 1978-08-23
Abstract: An alarm system is designed to detect a change of load on a supporting hook. The system is particularly suited to security systems for the protection of hanging items in museums etc. The load hook (9) is supported on cable (4) that passes with clearance through a contact plate (6). The cable position depends upon the action of a coil spring. Once loaded the cable settles in the mid-position and the circuit across two terminals (11, 12) is not made. Any attempt to remove the load allows the spring to bring the cable into contact with the plate and the coupled alarm is triggered.

Inventor: GLUENDER GEORG DIPL ING
IPC: H04N7/173
Filed: 1978-09-13
Abstract: A closed circuit t.v. subscriber answering system provides two-way traffic between the transmission station and the subscriber. It is used on a hierarchical network system where subscriber stations are connected to distribution stations via second order networks.

A cycle is divided into an equal number of data blocks as distribution stations. Each data block contains an equal number of interrogation symbols as the subscribers. The main station (1) transmits the interrogation symbol at time intervals (11) greater than the longest transit time (10) in a second order network. The information blocks (9) are transmitted at intervals (14) greater than the longest transit time (13) between two distribution stations in a first order network.
Patent DE-2841946-A1 (DE)
Inventor: SHIDA MASAHARU
IPC: G04C3/14
Filed: 1978-09-27
Abstract: A driver circuit for a stepping motor having a coil, a stator and a rotor receives pulse signals from a pulse signal generator to rotationally drive the rotor. A rotation detection circuit comprises switching circuitry switchable between a high impedance loop formed of the coil and a high impedance element and a low impedance loop formed of the coil and a low impedance element, and means for detecting the voltage induced in the coil. After a pulse signal is applied to the stepping motor, the switching circuitry forms the high impedance loop and the detecting means compares the voltage developed across the high impedance element with a predetermined voltage to thereby detect the rotation and non-rotation states of the rotor. This is a divisional of application Ser. No. 966,115, filed Dec. 4, 1978, now U.S. Pat. No. 4,326,278.
